Paul's code is now in p9p.  Because the code can read
where your finger is on the mouse when you click, it can
pretend there are three different buttons when in fact
there's just one.  Chording works too, and it's all very natural.
It's quite elegant actually.  Kudos to Paul.  I hope that the
code will let one use the new clickable laptop trackpads as
3-button mice too, but I haven't tried that.

In fact it has made the trackpad unusable for me as I can't highlight anything with a click of any kind at this point.  Now if you have a mac multi-touch laptop, you're going to have get an external mouse.
 

However, if you have any tendency toward repetitive strain injuries,
you might want to avoid the Magic Mouse: not being able to touch
the mouse with the non-clicking fingers means a less relaxing grip,
especially when pretending its tiny surface has three buttons.
After maybe four hours of use, my wrist had started to hurt.

(I had a bad desk twelve years ago that hurt my wrists, and
now they're sensitive to this kind of thing.  But I'm not the only
one - http://boingboing.net/2009/12/03/magic-mouse.html - and
presumably that guy wasn't using 3 buttons or chording.)

Back to the Evoluents for me.

I'm back to using trackballs :-) .  And I guess I either have to fix this problem with the trackpad myself or wait for a fix or use an external pointing device.
